Hoping someone can help me figure out what to do next. I get the single beep alarm that the engine is not reaching operating temp at idle (~140 degrees). I changed the water pump and get a good stream. I also change the water pressure sensor as I was getting readings all over the place from 0 - 29 psi and the new pressure sensor seems to have solved that issue. I changed the poppet valve, tried 2 thermostats and tested them in water to make sure the open at the ~140 degrees. I also changed the temp sensor near the top cylinder but still have the same issue of not getting above ~106 degrees at idle. What else can I do? I am getting frustrated and I am hoping I am not causing damage as the motor runs fine except for the idle temp.
Dan @ European did service my fuel rail and injectors over the winter as well and that is all doing fine. Just this idle temp has me going crazy chasing it.
Many thanks!
